[0037] The electric push rod assembly drives the positioning pin assembly to move, and the positioning pin switches between a first state of being inserted into the positioning hole and a second state of being withdrawn from the positioning hole.

[0038] In this embodiment, if Figure 1 and Figure 2 As shown, a plurality of positioning mechanisms 200 corresponding to the positioning holes are arranged at the bottom of the box body 100. When the electric push rod assembly in the positioning mechanism 200 drives the positioning pin assembly, the positioning pin 202 in the positioning pin assembly switches between the first state of being inserted into the positioning hole and the second state of being withdrawn from the positioning hole, so that the body of the cache box can be quickly converted between the positioning state and the movable state when used as a fire cache box, thereby quickly transferring the battery box when thermal runaway occurs, thereby avoiding more serious losses.
